A novel bismuth-based hybrid material with highly activity for fast removal of rhodamine B under dark conditions

Crystal structure, computational study, optical and vibrational properties of a new luminescent material based on bismuth(III): (C10H28N4)[Bi2Cl10]

“…These Bi-Cl distances, shortest than the sum of the Van der Waals radii of the bismuth and the chlorine atoms 3.82 Å, are in good conformity with data for similar compounds [54][55][56][57].…”

“…dimer and taking into account the calculations carried out here [14,49,[54][55][56][57][58][59]. The HF/SDD calculations for the anionic sublattice made up of isolated Bi2Cl10 dimers composed of two BiCl6 distorted octahedra sharing one edge predict the vibration modes between 230 and 32 cm -1 .…”

Dimethylammonium iodide stabilized bismuth halide perovskite photocatalyst for hydrogen evolution

“…In particular, bismuth halide perovskites have shown better stability under ambient atmosphere in solar cells in comparison with traditional lead based perovskites [22]. Although some works have demonstrated that the bismuth halide hybrids show catalytic activity in lower concentration of hydrohalic acids or even water [23,24], their stability issue in aqueous solution is still lacking. In addition, encapsulation strategy has been explored to stabilize metal halide perovskites in water [25,26].…”

Low-dimensional bismuth(III) iodide hybrid material with high activity for the fast removal of rhodamine B

“…In water, catalyst 1 could react with H 2 O, forming H + and OH À ions. The H + ions make RhB protonated, which leads to electron transfer between the protonated RhB and OH À , while at the same time, electrons from the dye molecules might transfer to the catalyst and further transmit to electron acceptors, such as OH À , resulting in the formation of hydroxyl radicals, which play a major role in the degradation of RhB over catalysts in the dark (Chu et al, 2018;Yan et al, 2016). Meanwhile, perovskite material 1 was gradually hydrolyzed to BiOI, as The UV spectra of compound treated with a 10.0 mg l À1 RhB solution at different cycles.…”

“…However, it is relatively rare for Bi-based perovskite-type materials with different hetero-cyclic organic cations. Recently, we have successfully prepared a series of lead-free ABX 3 -type perovskites, for example, (C 5 N 2 H 9 )[CdCl 3 ] and (C 4 N 2 H 7 ) 2 [BiCl 5 ] (Chu et al, 2017(Chu et al, , 2018, which could be applied for the detection of volatile organic solvent molecules or the fast degradation of rhodamine B (RhB) at room temperature under dark conditions.…”
